Exclamation laptop not recognizing ethernet cable
I have a 6-month old Toshiba laptop that for about the first 3 months recognized my wired ethernet network. However, for a while now when I plug it in, nothing happens. I have had to use my desktop. I have tried the cable on the desktop and it works fine. In addition to my laptop, I have an HP desktop, also very new, and a 5- year old Mac, all plugged into a Linksys router. We have no WiFi(), so that's not an option. All my drivers are up-to-date, and I have tried enabling and disabling the ethernet and wifi ports.
Any help would be greatly appreciated.
Thanks!

can we see a device manager screen shot and ipconfig /all


------------------------------------------------------------------------
ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

We would like to see the results from ipconfig /all post back the results in a reply here

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
Next
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste
------------------------------------------------------------------------



------------------------------------------------------------------------
Device Manager
Post back the results in device manager
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

windows key and pause Key should open to allow device manager to be seen on laptops may need to use windows key + FN key + Pause Key
if not then

Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
windows 7
start > control panel> System and Security> Device Manager

network adaptors, click on the + > post back the devices listed there
are there any ! ? or X


post a screen shot of the device manager - network adapters

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here

Device manager and ipconfig/all
Here is the ipconfig/all command screenshot and the Device Manager screenshot.
I'm pretty sure the device manager will not help very much because it shows all devices functional.
However, I included both.
Thanks!

EDIT
< moderator - pasted ipconfig /all>

would you do a tcp/ip reset

also what firewall/security suite do you have - a trial version still on the PC - like Norton, mcafee etc


------------------------------------------------------------------------

TCP/IP stack repair options for use with Vista/Windows 7

Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Note: Type only the text in bold for the following commands.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
and press enter

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
and press enter

Reboot the machine.

If you receive the message
The requested operation requires elevation.
Then please open the command prompt as administrator - as requested above
Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Please note and post back - if you receive the message
Access is Denied

Post back the results here - we need to know these commands worked correctly
rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

You "have no WiFi" but your ipconfig /all shows a wireless connection.

I have performed these commands successfuly, and no error messages or messages whatsoever appeared upon rebooting.
Terrynet- My WiFi router has some problems and is unreliable. I would like wired internet access when the router is not working. It shows up as "limited or no internet access". that is probably why it shows up on the ipconfig.
Thanks!

would you provide details of how everything is connected - make and model of any modems and routers

Is it the modem or the router you want to connect by cable to - is this the same router thats having problem ?

please provide as much detail as possible and how the other devices are connected
